Lafayette transmitter was a large facility used for transatlantic VLF-transmission, located at Marcheprime, Aquitaine, France. The Lafayette transmitter used an antenna, which was carried by eight free-standing lattice towers (each 250 metres tall) with triangular cross-sections, which were the second tallest free-standing towers in France. In 1944 the installations of Lafayette transmitter were destroyed by retreating German troops. The last of the towers were demolished in 1953.
